Business: Automotive parts, crystal oscillators, crystal oscillators and crystal flakes, video electronic devices, liquid crystal display devices, optical device parts, optical communication parts, industrial machinery and equipment, small precision metalworking parts, etc. We are involved in various fields.
◆One-stop sales 【Crystal products】
We can sell crystal products from processing to assembly in one stop.
We can sell crystal wafers, crystal flakes, and finished products separately.
◆Production from material to processing 【Ceramic products】
We purchase bearings and magnets used in watches from materials and produce them as proce ssed products.
We process from granulation to molding and firing and finish.
●Possible application products
We are expanding horizontally using our processing technology, such as using ceramic products for watches for computer cooling fans.
◆All technologies are assembled 【MEMS products】
This is a product that can meet all customer needs by integrating the "microfabrication, functional thin film, molding, and bonding technologies" we have.
Our strengths include bonding and sealing of dissimilar materials and vacuum sealing.
●We accept processing orders Our MEMS foundry accepts all or part of the processing orders from our customers using the above technologies.
------------------------
Utilizing our metalworking technology that creates small precision parts rooted in watchmaking, our company has been supplying customers with small, high-precision parts for many years, through consistent production lines from process design to processing, assembly, and functional testing, and the unique development of our own processing machines.
Also, producing parts efficiently with high precision using brittle materials is another unique core technology of our company. By integrating materials technology, ultra-precision machining technology, thin film technology, and bonding technology, we are creating high-quality functional device products such as high-precision parts made of ceramics and crystals, as well as liquid crystal devices and sensing devices.
Continuing to provide products with high added value to the market is a great dream of our employees. Towards the realization of that dream, we contribute to the creation of new value through manufacturing driven by each individual's spirit of challenge.
